  A gear-tooth sensing system consists of the sensor IC, a back-biasing magnet, and a target. The system requirements are usually specified in terms of the effective working air gap between the package and the target (gearteeth), the number of switching events per rotation of the target, temperature and speed ranges, minimum pulse duration or duty cycle, and switch point accuracy. Careful choice of the sensor IC, magnet material and shape, target material and shape, and assembly techniques enables large working air gaps and high switch-point accuracy over the system operating temperature range.
